Quick Reference

The drill-them-cold blocks: every memory acronym, the V-speed table, and the weight & balance method. Built for the night before — and the parking lot outside the DPE's office.

Memory acronyms

V-speeds

Worked example — PA-28-151 Warrior(swap in your aircraft's POH numbers)

V-speed	Knots	Notes
Vne	153	Red radial line
Vno	122	Top of green arc
Va (2,325 lb)	~108	Decreases at lighter weight
Vfe	100 / 109	Serial-number split — confirm yours
Vso	50	Bottom of white arc
Vs1	56	Bottom of green arc
Vx	~66	Best angle — obstacle
Vy	~76	Best rate
Best glide	~74	Engine-out

The 1973–76 PA-28-151 AFM publishes MPH CAS; a knots panel won't match a generic "PA-28" chart. Full table with MPH on the Performance & Limitations task page.

Weight & balance method

List each station's weight: empty aircraft, front seats, rear seats, baggage, fuel (gal × 6 lb for 100LL).
Multiply weight × arm = moment for each station.
Sum the weights; sum the moments.
Total moment ÷ total weight = CG.
Confirm weight is at or under max gross and CG is inside the envelope at that weight — check the envelope, not just the numbers.

Worked scenarios (including the over-gross trap case) live on the Performance & Limitations task page.

How to prepare

Memorize your V-speed table first — and be ready to explain where your numbers come from in your AFM.
Pull out your actual POH/AFM and current W&B sheet. Empty weight and useful load vary with installed equipment; representative numbers are not authoritative for your tail number.
Lead with the modernized facts an examiner may probe: the Aviation Weather Handbook as the weather reference, GFA replacing the FA, and the discontinued FA / Weather Depiction Chart / DUATS / Flight Watch.
